Addressing Methods
Because there are manydata registers,
h memory
function requires you to specify which register you wish to
use. You can use several methodsto address
a particular
data register.If you makea mistake w!

Addressing
In the examplesonthe previous page, a three-character
field is used to address a particular data register (004).
Whenyouuse such long-form addressing, you must
includeall three characters, including leading zeros for
addressesless than 100.
Whenreferring to a data register whose address is less
than 100, you can reduce keystrokes by omitting any
leading zeros in the field. The calculatorsupplies the
leading zeros whenyoupress any key other than [HELP],
[CLEAR],
/ [ON], or a number(digit) key.
For example, to use short-form addressing to recall the
contents of data register 004 and add 12.3, press
4
12.3 [=]. (When youpress [+], the 4 is accepted
as the entire field for data register 004.)
You mayfindit easier to rememberan alphabeticletter
than anumber. Youcan use the letters A through Z to
referto thefirst 26 data registers (000 through 025).
Whenyouuse such alphabetic addressing, the memory
operation is completedas soon as youentertheletter.
For example, to recall the contents of data register D
(register address 003), press [ R C L ]
D.
Anaddressing method used primarily in programmingis
indirect addressing. This methodlets you refertoa
particular data register by storingits register address ina
seconddata register.
Indirect addressingis discussed in detail in the TI-95
Programming Guide.
